输出值大于0

Question

我想使用以下脚本输出计数：

@find /c /i "Error   : -2" "\\Sc0320svr0001\e$\Users\SC0320POS0003\E2ELOGS\*.dbg" >>output.txt

但是，我只想导出大于0的值。

当前输出：

---------- \\SC0320SVR0001\E$\USERS\SC0320POS0003\E2ELOGS\PED_20140812_092355.DBG: 4

Answer 1

尝试测试输出的最后一个字符：

@echo off
setlocal enabledelayedexpansion
for /f "delims=" %%a in ('find /c /i "Error   : -2" "\\Sc0320svr0001\e$\Users\SC0320POS0003\E2ELOGS\*.dbg"') do (
  set "$line=%%a"
  set "$lastchar=!$line:~-1!"
  if !$lastchar! gtr 0 echo %%a >>output.txt
)

Answer 2

@find /c /i "Error   : -2" "\\Sc0320svr0001\e$\Users\SC0320POS0003\E2ELOGS\*.dbg" |findstr /i /v /c:": 0">>output.txt

Findstr开关的find含义不同。

&    seperates commands on a line.

&&    executes this command only if previous command's errorlevel is 0.

||    (not used above) executes this command only if previous command's errorlevel is NOT 0

>    output to a file

>>    append output to a file

<    input from a file

|    output of one command into the input of another command

^    escapes any of the above, including itself, if needed to be passed to a program

"    parameters with spaces must be enclosed in quotes

%variablename% a inbuilt or user set environmental variable

!variablename! a user set environmental variable expanded at execution time, turned with SelLocal EnableDelayedExpansion command

%&ltnumber> (%1) the nth command line parameter passed to a batch file


% or %% (%A or %%A) the variable in a for loop. Single % sign at command prompt and double % sign in a batch file.
